BEET SLICER OF THE DRUM TYPE.

Application filed December 9. 1927, Serial No. 238,933, and in France December 14, 1926.

This invention has for its object improve,

ments to boot slicers of the drum type, which improvements allow to improve their operation and to reduce the motive power absorbed by these machines. The main features oi the invention are that the stationary disc and the revolving druin are provided at their edge with a conical portion. that the moving part is furthermore provided with scrapers and that the apparatus comprises a device a]: lowing the injection 01 water or steam durlng the operation.

On the annexed drawing a particular enihodiinent oi the invention is shown schematically and only for illustration.

big. 1 is a cross section of a beet slicer of the drum type provided with. the improvements which are the object of this invention.

Fig. 2 is a section along I1II of Fig. 1.

Fig. shows in detail at enlarged scale the position of a scraper.

According to the invention, water (or steam) is directed under pressure, by means of a pipe 1 passing through the comma shaped portion 2 of the boot slicer, as close as possible to the center oi the apparatus, between the revolving drum 3 and the stationary disc 4-. The slices contained in this space are diluted and the mixture of slices and water receives from the drain a rotating movement which is sutlicient to throw it, under the action of the centrifugal force, toward the periphery of said druni. At its periphery the drum shows an internal conical border which is connected to the straight portion by means of a suitable curve 6 which cam-10s the slices to be thrown toward the intcrior oi the boot slicer and which prevents said slices of entering in the annular space 7 left between the lru n and the surface ot the stationary disc, where tl'iey might agglorm crate to tor-1n a block on aceo an t of the sweet juice they contain. This would produce a considerable rubbing on the whole surface 01' the drain, which would cause an increase of the power requirements, a rapid wear 011 the drum and on the disc and a great axial thrust on the thrust bearing of the boot slicer. The stationary disc is also provided with a conical border 8 which corresponds to the conical portion 5 of the drum.

In order to complete this cleansing, scrapers 9 are attached to the internal border 5 of the drum said scrapers 9 being suitably disposed according to the direction and the speed of rotation oi? this member. The greater part of the slices is thus thrown steadily toward the interior of the beet slicer whether it tends to penetrate in the annular space 7 or to leave this space mixed with the injection water.

This water or steam injecting device should be used three or tour times t aily while the factory is running.

The invention is not limited to the boot slicer shown on the drawing which is given only for illustration, but it can also be applied to any beet slicer oi the drum type in which above mentioned results are contemplated.

I claim: p

1. A beet slicer of the (111111) type comprising in combination a rotating druni with an internal conical border and a stationary disc with a portion of corresponding conical shape.

2. A beet slicer ot' the drum type comprising in combination a rotating drum with an internal conical border provided with suitably disposed scrapers and a stationary disc with portion of a conical shape corresponding to said conical border.

3. A beet slicer oi the drum type comprising in combination a rotating dru-ni with an internal conical border provided withsuitably disposed r pe'rs, a stationary disc with a portion of a .conical shape corresporuling to said conical border and a fluid injecting device adapted to work during the operation of said beet slicer.

In testimony whereof I have signed name to this specification.

ABEL MAGUIN.
